For this assignment, you will help an independent farmer get the right amount of fertilizer for their land so they can optimize their production. You need to create a program that:

(1) Prompts the user to enter the size (width and depth) in feet. Calculate and output the wall's area (as an integer).

(2) Extend the program to calculate and output the amount of fertilizer in pounds needed for the field (floating point). Assume a pound of fertilizer covers 1000 square feet (store this value in a variable). Output the amount of fertilizer needed using the %f conversion specifier.

(3) Extend the program again to calculate and output the number of 1 pound bags needed to fertilize the field. Hint: Use a math function to round up to the nearest pound.
